1 Claim.

My invention relates in general to improvements in hoists, and in particular to a hoist for use in railroad box cars in the storing and transporting of automobiles.

It is well known to those skilled in the art that in certain types of apparatus used in box cars for storing and transporting automobiles, the hoisting mechanism is made a permanent part of the box car. This hoist is usually fastened near the top of the box car and to the side Wall thereof, immediately under the roof. The space is, therefore, much constricted and the hoist casing is so close to the place where it is secured that it is difiicult to properly rivet or otherwise secure the bracket holding the hoist in place.

I-Ieretofore, the hoist has been made integral with the bracket and, therefore, has been a definite, fixed part of the car.

The principal object of my invention has been to provide a hoist made with a separate, detachable bracket which can be conveniently secured initially to the box car by riveting or otherwise, and which is of such nature that the hoist casing may be detachab-ly fastened thereto.

Moreover, it is a novel characteristic of my invention that it has two chain load-lift wheels carried by the hoist shaft and arranged at one side of the hoist, and a detachable bearing for supporting the shaft independently of the bearings formed in the casing.

The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which:

Fig. 1 shows a transverse, sectional elevation of a box car showing a hoist, of the type to which my invention is applicable, secured in place.

Fig. 2 is an enlarged, fragmentary, sectional view of one of the corners at the upper part of the box car and shows an end view of the hoist.

Fig. 3 is a plan View of the hoist.

Fig. 4 is a perspective View of the hoist bracket forming part of my invention.

In Fig. 1, I show a box car 5 having the usual side walls 6 and roof 1. The hoist I3, to which my invention is particularly applicable, is designed to control an automobile supporting frame 9. The frame 9, only one portion of which is shown, is designed to be elevated within the box car by means of the load chains H and I2 of the hoist l3. The chain ll falls immediately from the load-lift wheel M of the hoist, and the'chain l2 extending around the load-lift wheel [5 (see Fig. 3), extends across the top of the box car over an idler l6 and then falls downwardly like the chain ll. Chains H and H are secured to one end of the frame 9, a separate hoist, not shown, being employed for controlling the other end of the frame.

Referring to Figs. 2 and 3, the hoist I3 is provided with a casing 20, made as is customary in two parts, and held together by means of bolts 2| and 22. This hoist is of the usual worm and worm wheel type and is provided with a hand chain 23 which passes over a hand chain wheel 24 in usual manner. The worm'shaft 25 of the hoist passes through the casing 29 and is journalled in suitable bearings 26 and 21, formed on the parts of the casing. One end of the shaft protrudes considerably beyond the bearing 27 and upon it are mounted the load-lift wheels l4 and 5. The shaft is of such proportions that it extends beyond the load-lift Wheels and is mounted in a separable bearing 28 detachable from the bracket independently of the casing.

My hoist is secured to the box car by means of a separable bracket 39. This bracket, as clearly shown in Fig. 4, is provided with a base 3| and flanges 32 and 33, which extend at right angles to the base. The base 3| is provided with suitable apertures 35 through which rivets 35 are passedwhen securing the same to the box car. A channel-iron 36 is secured to the upper part of the box car, and it is to this that the bracket 33 is riveted, asshown. The flanges 32 and 33 are each formed with apertures 31 and 38, respectively. The bolts 22 of the hoist casing are designed to pass through the openings 31 in the flange 32, whereby the hoist proper may be secured to the bracket. The separable bearing 28 is provided with a flange 39 which provides means for independently securing it to the flange 33 by means of bolts lfl which pass through the openings 38 of this flange.

From the foregoing, it will be obvious that the hoist may be detached from the hoist bracket 30 which may then be conveniently and securely riveted or otherwise fastened in position within the box car. fastened, the casing 29 of the hoist may be secured to the flange 32 of the bracket by means of the bolts 22, and the separable bearing 28 slipped over the end of the shaft 25 and secured to the flange 33 by means of the bolts 40.

Another advantage of my invention is that should it become necessary to replace either of the load-lift wheels, the separable bearing 28 may be removed by removing the bolts 40 and either or both of the wheels may be withdrawn from After the bracket is securely 4 the shaft and replaced by others, after which the bearing 28 may be readily reassembled and secured in place. Furthermore, if it should become necessary to repair any portion of the hoist, the same may be conveniently removed from the bracket and, after repairs are made, may be again readily secured thereto, or the defective hoist may be replaced by another hoist of the same type,

Obviously, some modifications of the details herein shown and described may be made withputdeparting from the spirit of my invention or the scope of the appended claim, and I do not, therefore, Wish tobe limited to the exact embodiment of the invention as herein shown.

Having thus described my invention, what I claim is:

The combination with a hoist, comprising a casing having a shaft extending therethrough, an independent bearing for the shaft, separable from the casing, and provided with a flange, of a bracket for supporting the hoist comprising a flat body and two integral, interspaced, attaching flanges projecting at right angles to said body part, means for securing said body part to a supporting surface, means for securing the casing to one of the flange brackets, and means for securing the flange of said independent bearing to the other bracket flange.
